Information-gathering strategies in hypothesis-testing

Three experiments were conducted to investigate the informational factors affecting the kinds of questions people ask for testing a hypothesis about another's personality. In Experiment 1, subjects formulated by themselves questions to test either the hypothesis that the interviewee is polite or the hypothesis that he is impolite. The boundary of the hypothesis was set either at an extreme or at an intermediate point on the trait dimension. Experiment 2 also varied the location of the boundary, but the hypotheses concerned extroversion-introversion and subjects chose questions from a predetermined list of questions that asked either about extroverted features or introverted features and that were either low or high in diagnostic value. Both studies found that subjects preferred to ask about features that are consistent with the hypothesis only when the boundary was extreme. In contrast, diagnostic features were preferred in all conditions. Experiment 3 showed that subjects' judgment of the diagnosticity of the various kinds of questions for discriminating at different boundaries paralleled subjects' preferences among these questions. These results were interpreted as providing support for the diagnostic strategy in social information gathering.     

Identity styles and hypothesis-testing strategies

The author investigated the manner in which individuals with different identity styles evaluate information relevant to a trait hypothesis-testing task. Identity style refers to how individuals seek, process, evaluate, and use self-relevant information. In a sample of U.S. college students, the participants with normative identity styles displayed confirmatory biases that served to protect and preserve the hypothesis being evaluated. The students with informational identity styles also used confirmation-biased hypothesis-testing strategies. The participants with diffuse-avoidant styles did not discriminate between confirmatory and disconfirmatory information.     

Sensitivity to social contingencies between 1 and 3 months of age

Infants' sensitivity to social contingencies was assessed. In Study 1, 1-month-old infants and their mothers interacted face-to-face in three types of imperfect contingent interactions: Normal, Non-Contingent and Imitation. One-month-old infants did not discriminate these conditions. In Study 2, 3-month-old infants were tested as in Study 1. At 3 months of age, infants gazed reliably longer in the Imitation condition and smiled reliably more in the Normal than in the Non-Contingent and Imitation interactions. These findings suggest a developmental transition in the sensitivity to social contingencies between 1 and 3 months of age. The relationship between the developing sensitivity to social contingencies and social cognition is discussed.     

Sensitivity to social and non‐social threats in temperamentally shy children at‐risk for anxiety

In the current brief report, we examined threat perception in a group of young children who may be at‐risk for anxiety due to extreme temperamental shyness. Results demonstrate specific differences in the processing of social threats: 4‐ to 7‐year‐olds in the high‐shy group demonstrated a greater bias for social threats (angry faces) than did a comparison group of low‐shy children. This pattern did not hold for non‐social threats like snakes: Both groups showed an equal bias for the detection of snakes over frogs. The results suggest that children who are tempermentally shy have a heightened sensitivity to social signs of threat early in development. These findings have implications for understanding mechanisms of early threat sensitivity that may predict later socioemotional maladjustment.     

Romantic relationship commitment and the threat of alternatives on social media

Although previous findings suggest a link between adults' use of social networking sites (SNS) and relationship commitment, research has been lacking. This study of 427 emerging and young adults (aged 18–32 years, 71.20% female) indicated that exposure to alternative partners on SNS was indirectly related to relationship commitment through the pursuing of alternative partners on SNS. The more frequently they were exposed to alternative partners on SNS, the more they engaged in pursuing these alternative partners, which negatively affected their relationship commitment. Furthermore, a positive relation between exposure and romantic comparison to alternative partners was found. Gender did not moderate these relations. The discussion focuses on the implications of the findings for relationship development.     

Sensitivity and specificity in affective and social learning in adolescence

Adolescence is a period of heightened affective and social sensitivity. In this review we address how this increased sensitivity influences associative learning. Based on recent evidence from human and rodent studies, as well as advances in computational biology, we suggest that, compared to other age groups, adolescents show features of heightened Pavlovian learning but tend to perform worse than adults at instrumental learning. Because Pavlovian learning does not involve decision-making, whereas instrumental learning does, we propose that these developmental differences might be due to heightened sensitivity to rewards and threats in adolescence, coupled with a lower specificity of responding. We discuss the implications of these findings for adolescent mental health and education.     

Job-decision inconsistencies involving social comparison information: the role of dominating alternatives

Previous research on joint versus separate preference reversals has demonstrated that individuals focus on social comparison information when they are evaluating a single option but focus on absolute salary when they are considering more than 1 option. Study 1 demonstrates that social comparison information is important in multiple option scenarios when an option favorable on social comparison dominates an inferior, 3rd alternative. Study 2 examines why dominating alternatives are so attractive by investigating the role that the value-shift, weight-change, and emergent-value models play in explaining the pattern of results obtained in Study 1. Results provide support for the value-shift and emergent-value models and further suggest that these 2 models may be interrelated, with justification (emergent-value model) mediating the relationship between the attractiveness of the attributes (value-shift model) and the attractiveness of the dominating alternative.     

Relationship between Anxiety Sensitivity subscales and social fears

This study examined the relationship between social fears and the three subscales of the Anxiety Sensitivity Index (ASI) in a non‐clinical, student sample. In particular, the unique variance that the three ASI factors accounted for in social scrutiny fears, social interaction fears, and fear during a social challenge was investigated. Anxiety Sensitivity–Social Concern (AS‐Social Concern) was hypothesised to account for a significant proportion of the variance in social fears compared to the other two subscales. Seventy one university students completed a series of psychological‐based questionnaires and participated in a social challenge (videotaped speech task). Contrary to prediction, AS‐Social Concern did not account for a unique proportion of the variance in social fears, but AS‐Physical Concern and AS‐Mental Concern did account for unique variance in social fears. Results are interpreted in light of recent findings on the structure of ASI.     

Utilitarian alternatives to Act Utilitarianism

One problem for any utilitarian alternative to act utilitarianism, such as rule utilitarianism, is the feeling that act utilitarianism is the most natural form of utilitarianism. Other forms seen unmotivated, inconsistent, or irrational. This argument is found in Smart, Foot and Slote. It turns on the assumption that utilitarianism must be motivated by the "teleological motivation", the idea that one must derive one's entire moral theory from the notion of the good. I respond that act utilitarianism itself has a problem from the point of view of the teleological motivation, a problem solved, surprisingly, by several utilitarian alternatives including rule utilitarianism.     

The influence of responsibility and guilt on naive hypothesis-testing

Three experiments were used to investigate individuals' hypothesis-testing process as a function of moral perceived utilities, which in turn depend on perceived responsibility and fear of guilt. Moral perceived utilities are related to individuals' moral standards and specifically to people's attempt to face up to their own responsibilities, and to avoid feeling guilty of irresponsibility. The results showed that responsibility and fear of guilt in testing hypotheses involved a process defined as prudential mode, which entails focusing on and confirming the worst hypothesis, and then reiterating the testing process. In particular, the results showed that responsible and guilt-fearing individuals: (1) tended to search prudentially for examples confirming the worst hypothesis and to search for counter-examples falsifying the positive hypothesis; (2) focused on the worst alternative, and tended to confirm it; (3) prudentially kept up the testing process, even if faced with initial positive evidence. Our discussion of the results emphasises how people are largely pragmatic in their hypothesis testing, using efficient cognitive strategies that focus on error minimisation rather than on truth detection. In a context of responsibility and guilt, the errors are linked to people's failure to face up to their own responsibilities, and are thus moral errors.     

The durations of attention to alternatives and re-evaluation in choices with two and three alternatives

In two experiments on choice the durations of attention to the alternatives were measured. In experiment 1 each subject chose one from two pictures; in experiment 2 the choice was one from three pictures. In both experiments the subjects understood that they would acquire the picture that they selected. In each experiment higher and lower conflict conditions were induced by offering subjects a choice between alternatives that had been evaluated either equally or disparately. In both experiments a significant relationship appeared between duration of attention and preference order with most subjects looking longest at the alternative that was preferred. In the comparison between conditions this effect was found to be stronger under lower conflict than under higher conflict; this difference reached a significant level in experiment 2. These results are contrary to findings by Gerard (1967), and this matter is discussed. The relevance of the results to other theories is examined. Inferences were drawn from dissonance theory about re-evaluation effects after decision, and evaluation changes were measured in the experiments. After adjustment for measurement regression, the data failed to reveal a significant chronic re-evaluation effect. Contrary to dissonance theory, the re-evaluation effect was weaker in the three-alternative choice experiment than in the two-alternative choice experiment.     

The psychometric properties of the Interpersonal Sensitivity Measure in social anxiety disorder

The Interpersonal Sensitivity Measure (IPSM) was developed to assess hypersensitivity to interpersonal rejection, a suggested trait of depression-prone personality (Aust NZ J Psychiatry 23 (1989) 341). Although studies of the IPSM and interpersonal rejection sensitivity have primarily been conducted in depressed populations, it is important to investigate interpersonal rejection sensitivity as a relevant construct in the assessment of social anxiety. This study examined the psychometric properties of the IPSM in treatment-seeking individuals with social anxiety disorder. The results of this investigation support the convergent and divergent validity and internal consistency of the IPSM in socially anxious individuals. An exploratory factor analysis of the scale was also conducted after the original factor and subscale structure was shown to be a poor fit for the present data. Three factors emerged (Interpersonal Worry and Dependency, Low Self-Esteem, and Unassertive Interpersonal Behavior), and 29 items were retained. Because they demonstrated negative factor loadings on Factor 2, it is suggested that the scoring for four items of the original IPSM be reversed. In summary, the revised IPSM assesses three aspects of interpersonal rejection sensitivity and appears to be a valid and reliable instrument for its assessment in social anxiety disorder.     

Major alternatives to the Classic Experimental Design

In summary, giving up any of the three defining features of the Classic Experimental Design has (at least) two important effects. Each concession creates a significant threat to our confidence that any improvements observed were actually attributable to the treatment we are studying. At the same time, each concession opens a door by enhancing, sometimes greatly, the feasibility of conducting work in settings that are the most true to everyday clinical practice. When the work is thoughtfully and responsibly conducted, the alternative designs can contribute to clinical knowledge in a way that is equally important to the contributions made by work that conforms to the stringent requirements of the "Classic" design. In the next article, we will discuss single-time-point designs, along with the important dictum, memorized by most everyone who has taken a course called "Introduction to Research" or "Introduction to Statistics" that correlation is not causation.
